Neuscharfeneck castle ruins are situated in the eastern part of the Palatine Forest. They lie on the western foothills of the Kalkofen Berg in the middle of a forest and are only accessible over forest tracks.
The first castle, dating to the 13th century, was considerably smaller than the present ruins. Of the Hochstaufen castle only a few remnants have survived.
The entire site measures about 60 by 150 metres. Its shield wall, built from ca. 1212 to 1232 and extended in the years 1470 and 1530, is the mightiest in the Palatinate, with a length of 58 metres and thickness of 12 metres. Within the shield wall there are relatively few usable passages, chambers and casemates. It therefore acted - apart from the hoarding (Plattform) that has not survived - primarily as passive protection for the castle behind it. The original entrance was over a drawbridge through the shield wall into the castle.
In the castle gardens, rare herbs such as White Henbane, Ingräu and Abbey Hysop were planted.
There is still a partially surviving gateway with a flanking tower. Four water basins, chiselled out of the rock in the 13th century, were used as cisterns, that were supplied with rainwater and, from the 16th century, with water from the Roßberg Spring, 2 kilometres away, over pipes made of clay or hollow tree trunks.
The 30-metre long upper castle (Oberburg) on the central rock was built from 1212 to 1232 as the first residential building but has unfortunately not survived, apart from its well and an inaccessible chamber and steps in the rock.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
